You will need: Phillips screwdriver, tester.
1. Press the clamp of the wiring harness block..
2.... and disconnect the block from the idle speed controller.
3. Remove the two screws securing the regulator to the throttle assembly..
4.... and remove the regulator from the hole in the throttle assembly.
Note. Please note: the connection is sealed with a rubber ring 1.
Note. Do not attempt to pull out or push in valve 2 of the regulator, as this may damage the regulator.
5. Switch the tester to ohmmeter mode and measure the resistance between the terminals «A» And «IN» regulator, and then between the terminals «C» And «D». The resistance should be in the range of 0.040–0.080 kOhm.
Note. There are no pin designations on the idle speed control housing, but their location can be determined by the corresponding designations on the wiring harness block.
6. When replacing the regulator with a new one, pay attention to the distance L between the end of the valve needle and the mounting flange - it should be no more than 23 mm. If this distance is greater, the regulator needle will rest against the seat of the throttle assembly and the regulator will be damaged when the fastening screws are tightened.
7. Before installing the regulator, clean the seat and air passage in the throttle assembly, as well as the surface under the regulator o-ring, from dirt.
8. Lubricate the O-ring with engine oil and install the regulator in the reverse order of removal. Screws of fastening of a regulator tighten the moment of 3–4 Нм.
